Why does tap water conduct electricity?
Answer: Dissolved ions
Why: In water the current is carried by moving ions, not by free electrons as in a copper wire.
-
What shape is a methane molecule?
Answer: Tetrahedron
Why: Flat drawings show methane as a cross, but in 3D its bonds spread to about 109.5° apart, wider than a flat cross allows.
-
What stops atoms from twisting around a double bond?
Answer: Pi bond
Why: The pi bond is the weaker partner, so a carbon double bond is less than twice as strong as a single one.
-
What has molecules that grab water at one end, oil at the other?
Answer: Soap
Why: In water, soap forms tiny balls called micelles, with oily dirt trapped inside and the water-loving ends facing out.
-
Which element pulls hardest on the electrons in a bond?
Answer: Fluorine
Why: Carbon-fluorine bonds rank among the strongest single bonds in chemistry, which is why Teflon, made only of carbon and fluorine, barely reacts.

How many chloride ions surround each sodium ion in salt?
Answer: 6
Why: Each chloride ion also sits among six sodium ions, so NaCl describes a 1:1 ratio of ions, not pairs.
